Two lakes have exactly the same amount of water in them. The surrounding environment is at the same temperature. You can presume the ground beneath each lake is a thermal insulator. Which lake would be more likely to freeze over in the winter - one that was large and shallow or one that was small and deep?

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

You hang a book bag on a spring scale and place the bag on a platform scale so that the platform scale reads 23.7n and the spring scale reads 13.8n. what is the magnitude of the force that earth exerts on the bag?
